Be it known that we, WILLIAM S. A'rwoon and FRANK DITCHFIELD, both ofthe city of Montreal, in the Province of Quebec and Dominion of Canada,have invented certain, new and useful Improvements. in Railway-- Cars,and do hereby declare that the following is a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the .same.

This invention relates to railway cars and is particularly adapted to beused in the construction of metallic freight or box cars, althoughseveral features of construction may be adapted for use in theconstruction of passenger cars.

The main object of the invention is to provide a metal car of neatappearance, comparatively inexpensive construction, out possessing greatstrength and durability.

A further object is to provide 'a car that can be properly ventilated atall times without subjecting the interior to drafts, and Withoutliability of leakage through the ventilating apertures.

The invention consists essentially of a car having an underframe of theusual type but having its sides, ends and roof consisting of sheet metalplates, said plates being provided at intervals with vertical integralribs or corrugations and being so constructed and arranged thatcontinuous ventilating fines or conduits are provided which extendfrom-the bottomof the sides upwardly tothe roof, said flues beinprovided on the interior of the car with su1table aperturesfor-admitting air to the interior thereof. B this means, the ribsformvertical strengthening ,members or stakes for the sides of the, car,said ribs at the same time comprising ventilating fiues which preventthe interior of the car from sweating or becoming damp, as is fully setforth in my co-pendingapplication, Ser. No. 571,327, filed July 11th,1910, of which this application is a division.

In the accompanying drawings which illustrate our invention and in whichsimilar numerals of reference refer to similar parts thereof Figure 1 isa'partial side elevation of a car constructed according to our in-\vention. Fig. 2 shews on the left half, a

partial plan view, and on the right, a partial hor zontal section, ontheline 10--11 of F g. 1. Fig. 3 is an and elevation of the car. Fig. 4shows, on the left half, a cross section onthe lme 12-13, and on theright, a cross sectlon on the line 14-15 of Fig. -1-. Fig. '5 1s apartial cross section showing the air flues. Fig. 6 is a detailed crosssection of one of the flues. Fig. 7 is an enlargedpartlal vertical crosssection on the line l4i'-15 of'Fig.,1 showing thearrangement of thedoors. ig. 8 is an enlarged partial horizontal cross section on the line1011 of Fig. 1, showing the arrangement of the doors. Fig. 9 is aslightly modified form of the flue shown in Fig. 6, adapted forpassenger car construction.

Referring more particularly to the parts, 16 designates the centersills, 17 the side sills,

and 18 the body bolsters, 19 the cross bearers or transoms, 20 the endsills, and 21 the longitudinal floor joists. comprising the under-frameof the car and arranged in the usual manner and according to the bestapproved construction. The floor boards 22 are laid transversely acrossthe joists 21, forming a permanent floor for the'car, although it willbe obvious that the construction hereinafter described may be used withhopper bottom cars.

The sides, ends and roof of the car are constructed of sheet metallates, the interior surface being plain an smooth, while the outside ofthe car has a series'of vertical ribs or stakes at intervals along thelength thereof, said ribs extending over the roof and being continuouswith the sides. These ribs are formed by crimping or corrugating themetal plates of which the upper frame is constructed, the ribs beingU-shaped, as shown in Figs. 6 and 9, and the edges of the plates bein vslight-1y oiiset so that the overlapping en 5 of the adjoining plate maybe fitted thereon to form a smooth or plain joint in the interior of thecar. The vertical side plates 23 are riveted at the bottom to the anglesections forming the side sills of the car and are riveted at the top tothe roof plates. The edges of the plates '23 are offset as indicated at24 so that. the adjoining a reg tta plate which over-lapsthe rib willfit closely without allowing the I'idge-to.proje ct from the surface.The Ufslfaped ribs 25,"formed' by corrugating the plates, are of sucharea 5 in cross section as to 'ermit a large volume.

roof, the-ribsv thus constituting ventilating flues. The plates 23 areoverlapped, as indicated in Fig. 6, across the ribs and are connected bymeans of suitable rivets 26 through the flanges on eachside of the ribs27 designatesthe end plates of the car, said plates being connected thevertical connecting strip 27 The en lates 27 and side plates 23 arebound toget er by the corner angle sections 28. At the ends of the cartransverse filler plates 29 are inserted be ow the roof plates to takeup the pitch of the roof, as in 'cated in Figs. 3 and 4.

The transverse roof plates 30 may extend across the car, or may beunited at the center of the car, and are bent over and downwardly at thesides to connect with the side plates. These roof plates are providedwith ribs 31 of the same contour as the ribs 25 on the side plates, butslightly larger in order that the ribs 31 will overlap the ribs 25forming a tight joint. These ribs 31 form the carlines of the roof andare turned downwardly as indicated at '32. The interior of the roof peakis provided with a lon- 85 gitudinal central air chanhel 33, whichserves not only to brace and unite the roof plates when they are formedin two sections, but is further adapted to permit the air from the fluesto be distributed through the to cars. The roof plates are riveted tothe side plates, and corner braces 34 serve further to strengthen thecar frame.

Within the ribs or carlines 31, we provide apertures 35 which open intothe central air as channel 33 and may, if desired, open directly intothe interior of the car, as indicated in Fig. 5. Apertures 36' in theair channel 33 permit the air to be distributed from end to end of thecar. It will thus be seen that the flues which are open at the bottomwill permit air to be drawn upwardly at the sides'of the car anddistributed evenly at the roof, the side stakes and carlines formingcontinuous fiues for this system of ventilation.

A'foot-walk 37 supported on the brackets 37, extend along the car roof.A filler 38 inserted at the juncture of the floor and sides preventsgrain and like material from to lodging in the'corners. To strengthenand stifien the car sides, we may, in some cases, use the longitudinalU-shaped stifieners 39 extending from end to end of the car and rivetedto the'interior at suitable intervals.

transverse stiii'eners 40, the ends 41 of which taper oii as indicatedin Fig.2.

"'-.."lhe"doorways 42 at the sidesof the car are closed by sliding doorssomewhat in the usual manner. At the doorways, the floor extendsoutwardly a suitable distance, being supported upon the extension angles43. The door 44 consists of a metal plate stiffened at the edges byperipheral flanges 45 and atthe top by an angle bar 45 .At one side thevertical Z-bar 46 forms the locking ja'mb, while the channel section 47forms the door jamb at the opposite side. The sealing plate 48 extendsalong the edge'of the door and overlaps the channel 47. The lintel ortop sill 49 is formed of a Z-bar having; one flange riveted to the sidesof the car, and having its outerflange overhanging the top of the door.The top of the Z-bar 49 forms the track for the running wheels 5 51,which are secured to the door in any approved manner. The lintel or topsill is supported at each end by suitable brackets 52. For passenger carconstruction, the ribs are slightly modified in form, the ends 53 0being flattened in order to secure same to the outside plate 54. Theribs 25 will, however, be similar in other respects, constitutingventilating fiuw and supports as above described. These flues may beprovided with dampers 55 at the bottom, or may be provided with slidingdampers in the interior of the car.

It will be seen that this construction of car besides being neat inappearance, will be very strong and durable, and will be particularlyadapted for carrying such freight as requires ventilation withoutexposure to rain or moisture. The car is well adapted for carrying livestock and, for this purpose, apertures for the admission of air may bemade in the fines at the interior of the sides of the car. F or carryinggrain, fruit, meat and the like, this construction of car will eliminatesweating or the accumulation of moisture, which is one of the greatestdifiiculties heretofore experienced in connection with the use of metalfreight cars.

It will also be obvious that for passenger cars, this system ofventilation will afford 1 great advantages over any system that can beused in cars of other types.

While we haveshown the preferred form of construction, it will beapparent that many modifications may be made Without 12 departing fromthe spirit of our invention.
